Tekanyo ea leakage inductance
Mokhoa o akaretsang oa ho lekanya ho lutla ha ho lutla ke ho potoloha mokhoa oa bobeli (oa mantlha) matsoelintsoeke, ho lekanya ho kenella ho matsoelintsoeke a matsoelintsoeke (ea bobeli), 'me boleng bo hlahisoang ke ba ho lutla ho hoholo (bobeli) ho isa ho ba bobeli (ba mantlha). Inductance e ntle ea ho lutla ha transformer ha ea lokela ho feta 2 ~ 4% ea inductance ea eona ea magnetizing. Ka ho lekanya inductance ea leakage ea transformer, boleng ba transformer bo ka ahloloa. The leakage inductance e na le tšusumetso e kholo ho potoloho ka maqhubu a phahameng. Ha o sotha transformer, inductance ea ho lutla e lokela ho fokotsoa ka hohle kamoo ho ka khonehang.

Phapang lipakeng tsa leakage inductance le leakage magnetic flux
Leakage inductance ke ho hokahana lipakeng tsa mantlha le tsa bobeli ha ho e-na le matsoelintsoeke a mabeli kapa ho feta, 'me karolo ea matla a khoheli ha e kopane ka botlalo ho ea bobeli. Karolo ea leakage inductance ke H, e hlahisoang ke ho lutla ha makenete ho tloha ho ea mantlha ho isa ho ea bobeli. Magnetic flux leakage e ka ba matsoelintsoeke a le mong kapa mapheo a mangata, 'me karolo ea ho lutla ha makenete ha e lebile moo matla a khoheli a fellang teng. Karolo ea ho lutla ha makenete ke Wb.
